shacl:class validation doesn't seem to observe inheritance

repro

1. create a class "Offering"

   {
   "@id": "Offering",
   "@type": [
     "rdfs:Class",
     "shacl:NodeShape"
   ],
   "shacl:property": [
     {
       "shacl:maxCount": 1,
       "shacl:minCount": 1,
       "shacl:dataType": {
         "@id": "xsd:string"
       },
       "shacl:path": {
         "@id": "name"
       }
     }
   ]
   }

2. create a child class "ServiceOffering" that is rdfs:subClassOf Offering

   
   {
   "@id": "ServiceOffering",
   "@type": [
     "rdfs:Class",
     "shacl:NodeShape"
   ],
   "rdfs:subClassOf": {
     "@id": "Offering"
   },
   "shacl:property": [
     {
       "shacl:maxCount": 1,
       "shacl:minCount": 1,
       "shacl:dataType": {
         "@id": "xsd:integer"
       },
       "shacl:path": {
         "@id": "price"
       }
     }
   ]
   }

3. create a "Charge" class

   {
   "@id": "Charge",
   "@type": [
     "rdfs:Class",
     "shacl:NodeShape"
   ],
   "shacl:targetClass": {
     "@id": "Charge"
   },
   "shacl:property": [
     {
       "shacl:class": {
         "@id": "Offering"
       },
       "shacl:maxCount": 1,
       "shacl:minCount": 1,
       "shacl:path": {
         "@id": "for"
       }
     }
   ]
   }

4. Create a ServiceOffering

5. Create a Charge referencing the ServiceOffering

expected

it works with no errors

actual

{"error":"db/shacl-validation","cause":"SHACL PropertyShape exception - sh:class: class(es) #{211106232533039} must be same set as #{211106232533465}."}

Of note: if you change the shacl constraint in Charge Class from

        "shacl:class": {
          "@id": "Offering"
        },

to

        "shacl:class": {
          "@id": "ServiceOffering"
        },

the error goes away so it seems It's not observing inheritance.
